TRANSFER MATERIAL STRIPPER Filed Sept. 1 9, 1951 O 1N VENTO/e By w F51 from/Ey Patented May 7,` 1935 UNITED ISTATES PATENT OFFICE This invention relates to typewriters, and more particularly to an attachment applicable to writdetached Written sheets.

ing machines and other manifolding apparatus for automatically separating the interleaved carbon or transfer material from used portions of associated record material. The use of continuous series connected manifoldingl stationery wherein continuous strips of carbon or manifolding material are interleaved between superposed strips of record material, the latter being transversely scored or perforated for detachment into successive sheets has become quite common. In such cases the carbon .strip after being but once used is also torn into short sections simultaneously with the detachmentof used portions of the record strips. Such use of one time carbon necessitates the further manual operation of individually separating thedetached sheets of carbon material from between adjacent This not only involves great waste of transfer material which the present invention is designed to conserve by guiding such material laterally from between the record strips prior to the detachment of used portions of the latter strips, thus preserving the carbon material in continuous unmutilated form for repeated use if desired, but it also involves waste of time necessary for such separation, thus to a considerable extent defeating the purpose of continuous series connected stationery.` 1

By the use of diagonal guides and an auxiliary take-up or feed device disposed in laterally offset relation and operated in unison with the paper feeding movement of the writing machine platen roll or other paper feeding devices, the carbon material is extracted from between the advancing record strips after they have passed the writing position and before the used portions thereof have advanced to the tear-off position.

The object of the invention is to provide a simple and inexpensive mechanism for automatically separating the interleaved carbon material from the written record sheets and incidentally conserving the carbon material for re-use.

A further object of the invention is to simplify the operation as well as the means for separating manifolding material after completion of the writing operation, whereby the mechanism will not only be cheap in construction, but Will be applicable to any standard type of writing machine, eificient in operation, automatic in action, of few operating parts and unlikely to get out of repair.

With the above primary and other incidental objects in view, as Will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation, or 'their equivalents, as hereinafter described and set forth in the claims.

Referring to the accompanying drawing Wherein is shown the preferred, but obviously not necessarily the only form of the embodiment of the invention, Fig. 1 is a perspectiveview of a portion of a typewriter to which the present invention has been applied. Fig. 2 is a detail sectional view on line 2-2 of Fig. 1. Fig. 3 is a. modification for use with a plurality of carbon sheets.

Like parts are indicated by similar characters of reference throughout the several views.

Referring to the drawing, I indicates a conventional form of typewriter of which 2 is the traveling platen carriage and 3 the platen roll. 'I'he present invention is an attachment for use in association with continuous series connected manifolding stationery which ordinarily consists of continuous record strips 4 4 which are transversely scored or perforated at spaced intervals for subsequent division upon such transverse lines into succeeding sheets, and interposed continuous strips or webs 5 of transfer or carbon material.

In the ordinary operation the carbon material is transversely torn into short sections simultaneously with the detachment of the succeeding sections of record material. This, however, as before mentioned involves a great waste of material which is thus used but once and necessitates the further tedious and time wasting operation of individually separating the detached sheets of transfer and lrecord material.

In the present construction the interposed strip or strips of carbon material are laterally diverted from between the record strips before the latter are sub-divided.

As illustrated in the drawing the present typewriter attachment comprises brackets 6 and 1 secured to opposite sides of the traveling platen carriage of the writing machine, the bracket 6 carrying an upright or supporting standard 8 from which extends downwardly into connection 4 with the supporting bracket 'l a guide rod 9 interposed between superposed record strips 4 and disposed in diagonal relation to the path of travel of the manifolding assembly as it passes the writing position and approaches the position in which the written portions of the strip are to be detached by being torn oif on the transverse division lines. There are as many guide rods 9 provided as there are transfer strips to be diverted from the manifolding assembly. Each transfer ystrip about'` the diagonally dis- 'Y andv detached from the supply portions of such record strips. The supporting bracket 6 is provided with a laterally extending arm I2 projecting beyond the typewriter frame which supports one or more reversely inclined guide rods I3 over which for convenience the strip is again turned and its direction of travel changed toone quite the reverse of the direction of travel past the writing position upon the platen roll 3. The guide` rod I3 is preferably revolubly mounted in its support or provided with a roller sleeve havingeither a. knurled or other tenacious surface. Coacting with such inclined guide I3 is anauxiliary feeding or take-up roller I4 carried upon a revoluble shaft I5 mounted in suitable journal bearings at the top of the supporting standard 8 and at the end of the laterally extending bracket arm I2. This shaft I5 carries a bevel gear pinion I6 intermeshing with a similar bevel gear pinion I'I onpthe end of an actuating shaft I8 journaled in suitable bearings upon the supporting brackets.I The actuating shaft I8 carries at itsinner end a gear pinion I9 intermeshing with asimilar gear pinion 20 upon the trunnion shaft of the platen roll 3. Thus as the platen roll 3 is rotated in the normal operation ofthe writing machine, it progressively advances in unison past the writing position the superposed record strips 4 4 and interposed carbon strip or .strips 5. lThe latter, however, changes its direction of travel upon passing about the guide rod 9 and is diverted laterally from the manifolding assembly. The rotary auxiliary feeding roller I4 oscillating in unison withthe platen roll 3, serves to draw the transfer strips laterally; from between the A record strips. Being timed for unison movement with the platen roll, it serves as a take-up pre;-

' venting accumulation of slack, wrinkles or buckling of the transfer strips, but doesnot put active strain upon the transfer strips nor interfere with the normal feeding operation of the platen roll 3 by which the transfer strip is advanced in unison with the record strips. The record strips project sufl'iciently beyond the diagonal guide rod 9 to be easily grasped for' the transverse tearing operation by which the written portions of the time in being able to detach the used portions of the record strips without the necessity of individually separating from therebetween the likewise detached portions of transfer material. In the modification disclosed in Fig. 3, a plurality of guide rods 9 have been shown to divert a plurality of transfer strips 5.

From the above description it will be apparent that there is thus provided a device of 'the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing f 'om the principle involvedor sacrificing any of its adless specific as to structural lfeatures, it is to be understood vthat the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into eiect, and the invention-is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims.
